+s390x System emulator
+---------------------
+
+QEMU can emulate z/Architecture (in particular, 64 bit) s390x systems
+via the ``qemu-system-s390x`` binary. Only one machine type,
+``s390-ccw-virtio``, is supported (with versioning for compatibility
+handling).
+
+When using KVM as accelerator, QEMU can emulate CPUs up to the generation
+of the host. When using the default cpu model with TCG as accelerator,
+QEMU will emulate a subset of z13 cpu features that should be enough to run
+distributions built for the z13.
+
+Device support
+==============
+
+QEMU will not emulate most of the traditional devices found under LPAR or
+z/VM; virtio devices (especially using virtio-ccw) make up the bulk of
+the available devices. Passthrough of host devices via vfio-pci, vfio-ccw,
+or vfio-ap is also available.
